It has already been proposed to prepare bearing a scale f, the graduations of which liquid milk by mixing milk powder with are marked 10. 20, 30, 40, 50, the numeral water.

Another feature of the int r up o hegraduation 20. removable vent-ion consists in providing the mixing vesst pper 9 which is provlded'with a. spring sel, which also acts as a feeding bottle, with f n ng devlce 7b of 11 known kind 1 then a removable stopper, the arran ement being placed on the bottle and the latter Closed such that the bottle is first use for shakin by pressing down the device it.

Each fifth graduation gether, produce normal milk, the apparatus is thus marked appropriately, viz. 50, according to the present invention provides 150, 200, 250 cubic centimetres. Thus, if a ready means for preparing and mixing water be poured into the mixing bottle up to milk in any required concentration, as any the graduation 100, the person filling the deviations upwards or downwards can be 50 bottle will know that it contains 100 cubic easily determlned or calculated by the doctor centimetres of water.

It is thus not necessary to transfer the milk from a special mixing vessel into a feeding bottle, as has been the case hitherto. This eliminates a further possible source of confeeding infants.

What I claim is: i

1. An apparatus for preparing liquid milk from milk powder, comprising in combination a mixing Vessel, a scale on the said mixing vessel, a measuring vessel and a scale on the said measuring vessel, the grad: nations of the two scales being so related to each other that similar graduations on the quantities of liquid and milk powder, which, when mixed together, constitute normal milk, as set forth.

2. An apparatus for preparing liquid milk from milk powder, comprising in combination a mixing feeding bottle, a removable stopper for closing the said bottle, when being used as a mixing vessel, a teat for replacing the stopper, when the bottle is being used as a feeding bottle, a scale on the mixing feeding bottle, a measuring vessel and a scale on the said measuring vessel, the graduations of the two scales being so related to each other that similar graduations on the bottle and the vessel indicate quantities of liquid and milk powder, which, when mixed together, constitute normal milk, as set forth.

In testimony whereof I have signed my name to this specification.
